Talc is a naturally occurring mineral that is composed of hydrated magnesium silicate. It is commonly found in metamorphic rocks and is often associated with other minerals such as serpentine, chlorite, and tremolite. Talc has a soft, greasy feel and is often used as a filler or lubricant in various industries.
Talc stone refers to the raw material that is mined from the earth. It is typically a grayish-white color and has a greasy feel due to the presence of talc in the rock. Talc stone is typically crushed and ground into a fine powder before it is used in various applications.
Talc powder is the finely ground powder that is produced from talc stone. The powder is typically very fine and has a soft, silky feel. Talc powder is used in a variety of industries, including cosmetics, pharmaceuticals, plastics, ceramics, and paint. It is often used as a filler or lubricant due to its unique properties, which include low abrasiveness, high chemical inertness, and excellent thermal stability.
But today we want to talk about the talc powder application is cosmetis
Talc powder is a common ingredient in many cosmetics and personal care products, particularly in the make-up industry. It is used as a base for many cosmetic products, including pressed powders, loose powders, and blushes. Talc helps to absorb excess oil and moisture, giving the skin a smooth and matte finish. It also helps to improve the texture and consistency of products, making them easier to apply and blend. Additionally, talc is often used as a filler in make-up products to increase their volume and reduce costs.
The fineness of talc powder used in cosmetics is generally very high. The particles are usually micronized, which means they are ground into very fine particles that are smaller than 10 microns in diameter. This fine particle size is important for several reasons. Firstly, it allows the talc to be easily blended into other ingredients, creating a smooth and even texture. Secondly, it helps to improve the adhesion of the product to the skin, ensuring that it stays in place for longer. Finally, it gives the product a soft and silky feel, which is highly desirable in many cosmetics. The exact fineness requirement may vary depending on the specific application and product, but in general, talc powder used in cosmetics should be very finely ground.
The grinding mill used for producing 1250 mesh talc powder is typically an ultrafine mill or a micro powder mill. These types of mills use high-speed mechanical impact to grind the talc into a fine powder.
use a combination of centrifugal force and air flow to grind the talc particles. The talc is fed into the mill and is ground by the rotating blades and the high-pressure air flow. The fine talc powder is then collected in a cyclone separator and discharged through a discharge valve.
use a similar grinding mechanism to ultra fine vertical roller mill, but operate at lower speeds and with smaller grinding media. The talc is fed into the mill and is ground by the rotating blades and the impact of the grinding media. The fine talc powder is then collected in a cyclone separator and discharged through a discharge valve.
Both ultra fine vertical roller mill and micro powder grinding mill are capable of producing talc powder with a particle size of 1250 mesh or finer. The choice of mill will depend on factors such as the desired particle size, production capacity, and cost.
